Title: Draining device for steel strip
Inventor: SHINTANI KOJI
IPC: C23G3/02
Filed: 2001-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a draining device for removing a remained pickling solution after a pickling treatment for the surface of the steel strip, which can solve a problem that a conventional device of removing water with only a wringer roll causes rust or stain pattern, because remaining water in both ends of the steel strip becomes excessive water adhering to the both ends of the surface of the steel strip, and needs to slow down a line speed for perfectly removing the excessive water, which leads to reduction of productivity. SOLUTION: The draining device for the steel strip comprises a wringer roll, of which the shaft is arranged perpendicular to a moving direction of the steel strip, for removing water adhered to the steel strip by pressing the top and bottom surfaces of the steel strip while rotating, and a slit nozzle which is arranged over and below the steel strip at a forward tilting angle of θ1 and an outward angle of θ2 degrees, for blowing and removing the excessive water off toward the both edges without spraying it to the wringer roll, by spouting high pressure air from a slanting rear position toward the both sides. Thereby, the device solves the above problems, eliminates a need for moving the wringer roll along a width direction so as to meet a change of the width of the steel strip, and prevents the life-shortening of the wringer roll.
